## Note about iperf version
The iperf example doesn't support all features in standard iperf. It's compitable with iperf version 2.x.
## Note about 80MHz flash frequency
The iperf can get better throughput if the SPI flash frequency is set to 80MHz, but the system may crash in 80MHz mode for ESP-WROVER-KIT.
Removing R140~R145 from the board can fix this issue. Currently the default SPI frequency is set to 40MHz, if you want to change the SPI flash
frequency to 80MHz, please make sure R140~R145 are removed from ESP-WROVER-KIT or use ESP32 DevKitC.
## Introduction
This example implements the protocol used by the common performance measurement tool [iPerf](https://iperf.fr/).
Performance can be measured between two ESP32s running this example, or between a single ESP32 and a computer running the iPerf tool

Steps to test station/soft-AP TCP/UDP RX/TX throughput are similar as test steps in station TCP TX.
If you want to improve the performance, need choose the sdkconfig.defaults config to build bin.
1. OS configuration: i. Enable Full cache; ii. CPU frequence 160M.
2. WIFI configuration: i. AMPDU enable; ii. Set RX Buffer Num to 26; iii. Set RX Packet Num to 7; iv. Set TX Packet Num to 6; v. Set WIFI CONTINUOUS RX Buffer Num to 4.
3. LWIP configuration: 1. Set TCP MSS to 1460; ii. Set TCP SND WND to 11680 (8 * MSS); iii. Set TCP RCV WND to 7300 (5 * MSS); iv. Set TCP RECV BOX to 7 (5 + 2).
The following data is calculated by PC iperf with ESP8266 iperf example.
|Mbits/sec|TCP TX|TCP RX|UDP TX|UDP RX|
|:-----:|:-----:|:-----:|:-----:|:-----:|
||15.29|10.56|24.33|42.04|
|Disable ampdu|15.50|11.36|24.12|21.61|
|CPU 80M|10.54|7.91|16.08|25.71|
|Disable Full cache|7.78|6.30|10.32|13.21|
